DRILLING DEVICE.

Application filed April 28, 1924. Serial No. 709,597.

To all w/eom it may concern:

Be it known that I, LOVIAS F. FRASER, a citizen of the United States, residing at Drumright, in the county of Greek and State of Oklahoma, have invented new and useful Improvements in Drilling Devices, of which the following is a specification.

This invention relates to walking beams of the character used in oil fields, and con templates a structure possessing greater strength and durability than those in present day use, and one wherein the beam can be adjusted laterally with respect to its support.

The nature and advantages of the invention will be better understood when the fol lowing detailed description is read in con nection with the accompanying drawing, the invention residing in the construction, combiuation and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a top plan view.

Figure 2 is a side elevation.

Figure 8 is an end elevation.

Referring to the drawings in detail, 10 represents the Sampson post of the supporting structure which is preferably formed of piping, and provided with a flange 11 which reposes upon a concrete base or foundation 12 as clearly shown in Figure 2. The upper end of this post is received by a casting 13 which is formed with lateral projecting apertnred lugs 14, the lugs receiving stay rods 15 which pass downwardly at opposite sides of the post 10, through openings in the flange 11, and have their lower extremities embedded in the concrete foundation 12. In :uldition to the lugs 14.- this .:astiug is also provided with a web 15 which siqnmrts a. fl'fll'lSVG'lfSO bolt 17, and terminally coi'inecied with the ends of this bolt are the adjacent extremities of adjust able truss rods 15%. 'lhese rods 18 are arranged in convergent relation and-have their lower ends embedded in the concrete blocks 19 which are arranged at opposite sides of the concrete foundation 12. The casting 13 is as clearly illustrated in Figure 3 provided with a substantially U-shaped portion 20 which forms a bearing for the trunnions 21 which project laterally from the lower part 22 of a clamp, the upper or cooperating part of which is indicated at 23. The part 23 is bolted or otherwise suitably secured to the part 22 as clearly illus trated in Figure 2. The walking beam formed from an appropriate length of cars ing or pipe is indicated at 24, and is received by the clamp just described, which allows this beam to be adjusted laterally with respect to its support, as well as rocked. upon the trunnions 21 carried by the clamp. Rising from the upper part 23 of the clamp is a plate 25 having obliquely disposed openings 26 to receive the adjacent ends of the truss rods 27, these rods being extended outwardly and downwardly to their point of connection with the beam 24, or in other words connected with this beam at opposite sides thereof and at points adjacent the free ends of the beam. The beam is provided with apertured lugs 28 to receive the ends of these rods. It is manifest, from the general construction and arrangement of parts, that I have devised a walking beam and support therefor which possesses maximum strength, and durability, and one wherein the beam can be conveniently adjusted laterally by simply loosening the clamp above described.

\Vhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, I claim:

1. In combination, a base, a post rising therefrom, a U-shaped bearing supported by the post, a two part clamp pivoted in said bearings, a tubular beam slidable within the clamp .for lateral adjustment with respect to the post, and. stay rods terminally co11- uected with the post and ground.

2. In combination, a base, a post secured thereto and. rising therefrom, a U hl'lHPQfl bearing supported by the post, a two part clamp, truunions n'ojecting from one part of the clamp and pivoted in said l'iearings, a

tubular beam, supported by said clamp and capable of lateral adjustment with relation to the post, a plate rising from said clamp in alignment with said. post, and truss rods terminally connected with the plate and the ends of said beam.

3. In combination, a base, a post rising therefrom, a casting supported on the post,

and including a substantially U-shaped bearing, apertured lugs projecting from the casting, stay rods passed through said lugs and connected with the base for holding the post positioned thereon, a two part clainp trunnions projecting from one part of the clamp and pivoted on said bearing, a tubular beam received by and supported by said
